Description

All EVOS® fluorescence imaging systems contain our unique, proprietary LED light cubes. This world-leading light engine outputs remarkable intensity over a short light path that delivers superior fluorophore excitation. Each cube contains an LED, condensing optics, and hard-coated filters. EVOS® light cubes are user-changeable and automatically recognized by the system. The Qdot® 705 light cube is ideal for use with Qdot® 705 and other fluorophores with excitation and emission maxima near 445 and 705 nm.

Revolutionary Light PathBy placing the LED light cube as close as possible to the objective turret, the number of optical elements in the light path is minimized. High-intensity illumination over a short light path increases the efficiency of fluorophore excitation, providing better detection of weak fluorescent signals.

Continuous Light IntensityMercury arc lamps can decrease in intensity by 50% in the first 100 hours of operation—plus, images acquired in different sessions cannot be quantitatively compared using mercury illumination without complicated calibrations. Because EVOS® systems have continuous light cube intensity, users can rely on consistent illumination and can compare quantitative results from images acquired on different days. Each light cube contains a precisely matched set of optical components to optimize the position, evenness, and intensity of the light beam. Digitally controlled LED light sources allow adjustment of illumination levels, dramatically improving control over photobleaching.

Less Expensive to Own and MaintainThe LED bulbs on the EVOS® systems are rated for >50,000 hours (~17 years), compared to 300 hours for a typical mercury bulb and 1,500 hours for a metal halide bulb. This translates to savings in the overall upkeep of your instrument.

EVOS® Hard-coated Filter Sets for Higher Transmission EfficienciesHard-coated filter sets are more expensive that soft-coated filters, but they have sharper edges and significantly higher transmission efficiencies that typically result in >25% more light transmission than traditional soft-coated filters. With the EVOS® systems' hard-coated filter sets, your light cubes cost less over time. Plus, you will have brighter fluorescence, higher transmission efficiencies, the ability to detect faint fluorescence signals, and better signal-to-noise ratios.
